Senior Propulsion Engineer – Engine Mechanical Design

Denver, Colorado

Start the Best Work of Your Career at Boom

At Boom, our remarkably small team built the groundbreaking XB-1 supersonic jet and designed the world's fastest airliner Overture. What made it possible? Exceptional people—driven, curious, and committed to building what’s never been built before.

Now, we’re applying that same approach to Symphony—the first jet engine purpose-built for sustainable supersonic flight. It will be the fastest development of a large-scale propulsion system in aviation history, and our engine mechanical design team is at the heart of it.

As a Mechanical Design Engineer, you’ll work shoulder to shoulder with aircraft designers, systems leads, and test engineers to architect the mechanical systems of Symphony—from concept through certification. You’ll design, optimize, and build the engine mechanical systems that make supersonic travel possible. And you’ll be there when it all comes together—when the Symphony prototype roars to life on the test stand this year, and takes flight just a few years from now.

If you’re the kind of engineer who chases understanding, thrives in the unknown, and gets energy from building what’s never been built—you’ll fit right in

Role Overview

As part of the Propulsion Team, you will:

  • Own the design features covering all the mechanically dynamic phenomena in the engine, including loads, actuation, rotordynamics, failure scenarios, and more
  • Develop technically sound design solutions to get symphony turbofan in the air as fast as possible!
  • Interpret, define and review tolerances and features on part drawings
  • Create physical layouts, models, and general arrangements of modules and whole engines such as 2D cross sections, 3D models, tolerance stackups, etc.
  • Contribute to the creation of whole engine models that incorporate structures, rotors, ducts, services routing, actuation, secondary air systems and thermal management
  • Collaborate on specifications and design requirements for each module and help lead cross discipline integration efforts
  • Act as the technical owner for all mechanical aspects of the engine, including fits, seals, mounts, joints and other components
  • Develop and implement plans for assembly and disassembly for both development and production
  • Beyond these specific things, there are many opportunities to get involved in all aspects of Symphony engine development and Overture propulsion system integration, including fabrication and testing.  Bring your curiosity!

Ideal Candidate

  • Bachelor’s or Master’s in Mechanical or Aerospace Engineering or related field
  • Expert-level experience with CAD systems such as 3DX, Catia or NX
  • Expertise in Geometrics Dimensioning and Tolerancing (GD&T)
  • Familiarity with a variety of manufacturing techniques used in gas turbine production (single crystal casting, hollow core fan blades, linear friction welding, additive manufacturing, etc.)
  • Leadership experience in designing turbomachinery modules and parts, as well as  throughout different phases of a program
  • Ability to clearly think through and communicate coupled engine and aircraft system level interactions
  • Willingness to both speak and listen, to give opinions and receive opinions, to consider all the data and be part of building the team consensus to move forward

What Will Set You Apart

  • Rig testing or engine testing experience
  • Supersonic jet engine design experience
  • Part 33 commercial certification experience
  • Experience with parametric modeling and PLM/PDM
  • Knowledge of heat transfer and structural analyses
  • Experience in the part disposition process
  • Background in developing design tools, methods or processes
  • Proficiency with Python or similar programming languages
  • A strong desire to avoid bureaucracy and move fast in a dynamic environment

We’re hiring at multiple levels of experience—whether you’re early in your career or bring decades of design expertise, we’d love to hear from you.
